The hot-water diesel-powered skid pressure washer from Water Cannon is powered by a Kubota Z602B1 or DH1005B1 engine. It offers up to 8 gpm at 4,000 psi, and comes with a General or Annovi Reverberi pump. A 12 VDC diesel-fired burner, 15-gallon poly diesel fuel tank, 40 amp charging system and battery box make it wholly self-contained. Beckett burners deliver 210 degree F max temperature, and a Schedule 80 coil with a molded combustion chamber offers access to hot water within seconds. A 3VX belt system with four belts, which are laser-aligned and factory tested, delivers balanced power transfer for complete control. Engine and pump oil drains enable simple maintenance. It has a safety pressure relief valve and thermo-sensor that prevents overheating in bypass mode. 800/333-9274; www.watercannon.com.
